From big things, like being able to run photoshop on a unix machine, to small things, like the command key not competing with control, beautiful text rendering, OS X is almost perfect, and it's been for so many year.

Why oh why can't they freaking update the damn hardware.

This is one of those situations where Apple secretive culture really hurts the entire industry.

A simple statement like, we screwed the Mac Pro redesign, but a new one is coming in June, we had manufacturing problems, or we are not interested in this market anymore, would be a lot better than simply selling a 3 year old computer for the same price.

That doesn't do anyone any good
